Belgium is facing significant travel disruptions due to mass protests and a nationwide railway strike starting on February 21 and lasting until March 2. The protests, driven by opposition to the new government coalition, are expected to draw at least 50,000 participants in Brussels. The strikes are primarily in response to proposed cuts in public services, pension reforms, and changes to unemployment benefits. While international train services may remain unaffected, local transport will be severely impacted. Passengers are advised to check for updates and may be entitled to refunds for delays.
